I bought my 99 GT in Dec. There were some mod done that I can see. But driving at 60 mph with 26 inch tires is around 2800 to 2900rpms in 4th gear. I don't now if the gears has been change.
www.ring-pinion.com web site calculator claims it is a 3.73. To think if this is true and I did'nt even know it. Performance is great and gas miliage is fine. I don't have a base to compare to, Going from 3.27 to 3.73. What do you guys think?
